Abstract

Described here is a microfabricated particle sorting device that uses a transient pulse of fluidic pressure to deflect the target particle. The transient pulse may be generated by a microfabricated (MEMS) actuator, which pushes a volume of fluid into a channel, or sucks a volume of fluid from the channel. The transient pressure pulse may divert a target particle into a sort channel.
